The dechirp technology can greatly reduce the hardware speed requirements for large data acquisition for a wideband phased array radar using a linear frequency-modulated signal. But the echo was associated with amplitude and phase fluctuations caused by in-band fluctuations in fast time. In the actual system, due to the dechirp distance window error, the fast time compensation coefficient may not be aligned with the actual frequency. A robust equalization method is proposed for dechirp channels in this paper.Simulation results show that this method can effectively achieve the robust processing for fast-time channel compensation.
